For this case, what we must do is equal the function to zero:
 b ^ 2 - 75 = 0
 From here, we clear the value of b. We have then:
 b = + / - root (75)
 We rewrite:
 b = + / - root (3 * 25)
 b = + / - 5 * root (3)
 So, the roots are:
 b1 = 5 * root (3)
 b2 = -5 * root (3)
 Answer:
 The roots of the quadratic function are: 
 b1 = 5 * root (3)
 b2 = -5 * root (3)

Amira and Mandisa sell balloon animals at different stands on the boardwalk. They each use a constant number of balloons per ani
MAXImum [283]

Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the number of balloons for x animals.

Amira uses 4 balloons for each animal.

For Mandisa, using the table using (20, 225) and (60, 25):

slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{25-225}{60-20}=-5

Therefore Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.
